HeavyWater said:A follow up question on the photino. I assume the photino travels at the speed of light. If that is true, why haven't we ever detected a photino? Could it be that only pure SUSY particles (not hybrids consisting of at least one quark and at least one square) produce photinos?
Supersymmetry is a theoretical framework in particle physics that proposes a symmetry between particles with different spin values. This symmetry predicts the existence of a partner particle for every known particle, with the same mass but opposite spin.
Supersymmetry predicts that the electromagnetic force and the weak nuclear force are actually different manifestations of the same underlying force, known as the electroweak force. This means that the particles and interactions involved in the two forces are related through supersymmetry.
Supersymmetry is important because it could potentially provide a solution to many unanswered questions in particle physics, such as the hierarchy problem and the nature of dark matter. It also helps to unify the fundamental forces of nature, giving a more comprehensive understanding of the universe.
So far, there has been no direct evidence for supersymmetry. However, many experiments, such as the Large Hadron Collider, are actively searching for signs of supersymmetric particles. Additionally, some theoretical predictions, such as the unification of forces at high energies, have been supported by experimental data.
If supersymmetry is confirmed, it could have far-reaching implications for our understanding of the universe. It could help to explain the nature of dark matter, provide a more complete understanding of the fundamental forces, and potentially even lead to the unification of all forces in a single theory. It could also have practical applications in technology and energy production.
